Two {110}-faceted gold nanostructures-rhombic dodecahedra and obtuse triangular bipyramids-have been synthesized via a Ag-assisted, seed-mediated growth method. The combination of a Cl--containing surfactant with a low concentration of Ag+ plays a role in the stabilization of the {110} facets. To the best of our knowledge, this is the first reported synthesis of a {110}-faceted bipyramid structure.
